| 摘 要： | 通过对井田边界条件、主要含水层的富水特征、断层的水文地质特征以及地下水的补给、径流及排泄条件的分析研究,认为二1煤层顶板的直接充水水源为顶板砂岩裂隙水,底板的直接充水水源为石炭系太原组上段石灰岩岩溶裂隙水,底板的间接充水水源为石炭系下段太原组灰岩岩溶裂隙水和寒武系白云质灰岩岩溶裂隙水;矿井充水通道为顶板砂岩、底板灰岩的裂隙和断层带。采用大井法对先期开采地段二1煤层-700m水平的矿井涌水量进行了预算：正常涌水量为947m^3/d,最大涌水量为1140m^3/d。结合邻近矿井的调查,认为计算的涌水量是可靠的,可作为煤矿建井设计和水害防治的依据。

| Abstract: | Through analyses of minefield boundary conditions, main aquifer water yield properties, fault hydrogeological characteristics and groundwater recharging, runoff and discharging conditions, considered that the No.II1 coal roof direct water filling source is roof sandstone fissure water, while the floor direct water filling source is the Carboniferous Taiyuan Formation Upper Member limestone karstic fissure water, indirect water filling sources have Taiyuan Formation Lower Member limestone karstic fissure water and Cambrian dolomitic limestone karstic fissure water, coalmine water filling channels have fissure and fault zones of roof sandstone, floor limestone. The virtual large diameter well method has been used to estimate No.II1 coal seam -700m level mine inflow in advanced extracting district： normal inflow is 947m^3/d, maximum 1140m^3/d. The estimated figures are thought to be reliable through investigation in neighboring coalmines, thus can be the basis of coalmine construction design and mine water flood control. |
